Sound device

Abstract

The present disclosure provides a sound device comprising a housing, a sound emitting unit received in the housing, and a flexible circuit board electrically connected to the sound emitting unit, the housing is provided with a snap structure for fixing the flexible circuit board, the snap structure comprises a bottom wall, several sidewalls extending from the bottom wall, a receiving space surrounded by the bottom wall and the plurality of sidewalls, and a snap portion extending from a surface of the sidewall toward the receiving space in a direction approaching the receiving space, the snap portion, the bottom wall, and the sidewalls form a groove, and the flexible circuit board is received in the receiving space with the periphery thereof stuck in the groove.

What is claimed is: 
     
         1 . A sound device comprising a housing, a sound unit received in the housing, and a flexible circuit board electrically connected to the sound unit, wherein, the housing is provided with a snap structure for fixing the flexible circuit board;
 the snap structure comprises a bottom wall, several sidewalls extending from the bottom wall, a receiving space formed by the bottom wall and the several sidewalls, and a snap portion extending from a surface of the sidewall towards the receiving space in a direction approaching the receiving space; the snap portion, the bottom wall, and the sidewalls form a groove; and the flexible circuit board is received in the receiving space and the periphery thereof stuck in the groove.   
     
     
         2 . The sound device according to  claim 1 , wherein the snap portion comprises a first snap portion and a second snap portion extending from two of the sidewalls opposite to each other, respectively. 
     
     
         3 . The sound device according to  claim 2 , wherein the first snap portion and/or the second snap portion extend vertically from the sidewall. 
     
     
         4 . The sound device according to  claim 2 , wherein the first snap portion and/or the second snap portion extend crookedly from the sidewall. 
     
     
         5 . The sound device according to  claim 2 , wherein a distance between the two opposite sidewalls is greater than a width of the flexible circuit board. 
     
     
         6 . The sound device according to  claim 2 , wherein the snap portion further comprises a third snap portion formed by extending from a sidewall disposed between the two opposite sidewalls. 
     
     
         7 . The sound device according to  claim 6 , wherein the third snap portion extends crookedly or vertically from the sidewall disposed between the two opposite sidewalls. 
     
     
         8 . The sound device according to  claim 1 , wherein the housing comprises an upper cover and a lower cover fitted with the upper cover, and the snap structure is disposed on the lower cover.
